GAS-BURNER.

SPECIFICATION forming part of Letters: Patent No. 603,661, dated May io,189s. Application filed July 29, 1897. Serial lla-646,407. (No m'odel.)

To all whom it may concern.-

Beit known that I, WILLIAM WESLEY SFE- LEY, a citizen of the UnitedStates, residing at- Brooklyn, Kings county, State of New York, haveinvented certain new and useful Im'- provements in Gas-Burners, of whichthe following is a` specification.

This invention relates to certain new and useful improvements in thatclass of gas-burners which are surrounded by globes or chimneys,havingfor its object to provide a burner which may easily and quickly belighted Without the necessity of removing the surrounding chimney or ofapplying a flame to the top of the chimney. y i

, With thisobject in view the inventionconsists in the novel features ofconstruction and arrangement of the parts hereinafter more fullydescribed.

In the accompanying drawings, forming a part of this specificationv andin which like letters and numerals of reference indicate correspondingparts, Figure 1 is a vertical sectional elevation of a gas-burnerembodying the invention. Fig. 2 is across-sectional view oftheinvention. Fig. 3 is a detail sectional view of a modified form ofburner.

Briefly stated, Vthe invention comprises a suitable burner and a globeor chimney and its frame normally surrounding the burner, the chimneyand burner being connected together and capable of' a' relativelongitudinal movement, whereby the top of the burnerisrenderedgaccessible for the purpose of lighting. Y 4

The invention also comprises an automatic lighting device which isarranged in proper position and operated to ignite the gas escapingthrough the burner-top Whenever the separation of the burner and itschimney is ef?V fected. Y

Referring more particularly to the drawings,-A designates the base ofthe burner,

which may be of any suitable form or construction and is adapted forattachment to a bracket or support B. As shown, the base yconstitutes acollar 1, which lsurrounds and is fixed to the bracket, and radiatingfrom the collar are arms 2, supporting at their upper ends a suitableholder 3 for. the chimney or globe C.

Extending upward from the collar l is a tube 4, in or upon which isadapted to slide aV tubularsli de 5, which supports at its upper end vasuitable burner 6. In the present instance thisgvburner consists of anannular chamber having a correspondingly-shaped air-passage provided inthe upper face `with a series of perforations for the escape of the gasand communicating with theinterior of lthetubular slide through shortconnecting radial passages 7. In order that the burner may be carriedbelow the chimney C as far as possible,- it is provided with a centraldome 8, which receives the upper end of the tube 4 when the burner isloosened, and preferably this dome projects above the top of theburnerandis so formed as to constitute a flame-deector., Y Surrounding thetubular slide 5 and longitudinallyadjustable thereon isa sleeve 5, fromwhich projects an annular iiange 5b, which may be adjusted to close `thelower end of the central air-passage 6?, as [shown in full lines, Fig.l, or be carried below the burner, as indicated in dotted lines,topermitair to flow through said passage.

Supported upon the interiori of .the holder 3 is an annular fiange 9,which Aserves to guide .the tubular slide 5 in its up-and-down movement.In some instances it maybe desirable to employ an ordinary Welsbachmantle l0 in connection with the burner, in which event the lower end ofthe mantle vsurrounds the flange 9 and is protected thereby from injury.by coming into Contact with the slide 5, and

preferably the fian ge is vertically corrugated .topermit the readylplacing or removal of a mantle upon it. 5 Whenever it is desired tolight a burner .which is surrounded by a chimney or globe,

Aas in the present instance, it is either neces-` sary to remove thechimney to render the tip vof the burner accessible or to turn on thegas while the chimney is in place and apply a lightn at the top thereofto ignite the volume 'of gas or of gas and air within the chimney. Thislatter, however, not onlyresults in smokingthe chimney, but frequentlycausespit to be broken by the explosion, and if a mantle be employed,owing to the extremely lfrail and brittle nature of the material ofwhich it is made, it is also very often fractured and rendered useless.The objections are, however, all overcome by arranging the tubularyslide which carries the burner to be moved IOO 'arms 2.

along the plane of the chimney, in order that a iame may be applieddirectly to the burnertip. When a mantle is used in connection with theburner, the tube 4 is provided with an air-opening 12, which when theburner and tubular slide are elevated is open to permit the passage ofair, together with the gas, through the slide and burner. When, however,the slide is in its lowered position, it moves over and closes theairopening. As a further means of regulating the -ingress of air throughthe opening 12 the tube 4 is provided upon its interior with a slide 13,which may be adjusted to either partially or wholly close the opening bymeans of a pin 14, which extends into the opening, it being understood,of course, that when a mantle is not used in connection with the burnerthe opening 12 is wholl y closed by its slide 13, and the sleeve 5a andits flange 5"A are adjusted to open the central airpassage 6a.

Cooperating with the burner 6 is a suitable automatic igniter D,arranged to light the burner whenever the tubular slide 5 is lowered. Asshown, the igniter is an electric one and comprises a yielding arm 15,secured to and insulated from one of the supporting- This armconstitutes an electrode and is provided at its upper end with a head orprojection 16, arranged to be struck and pressed back by the burner 6 asit is raised and lowered, and connected to this head 16 is aconducting-wire leading from a suitable battery or other source ofelectrical supply. (Not shown.) The burner 6 is in the electric circuitwith the arm 15 and constitutes a second electrode. It l,will thus beseen that whenever the burner 6 is lowered it makes contact with thehead 16 of the arm 15 and presses it back until the top edge of theburner is carried below the head, causing the separation of the head andburner, and thereby generating a spark which will ignite the gas flowingthrough the openings of the burner.

The bracket B is provided with a passage which communicates with andsupplies gas to the vert-ical tube 4, and this passage is controlled bythe usual cock 17. Likewise located within the passage above the cock 17is a bypass valve 18, arranged to be operated through a lever-arm 19,and connecting this lever-arm with the tubular slide 5 is a link 20.Normally when the burner is elevated within its chimney the valve 18 isopen; but when it is desired to light the burner the cock 17 is openedand the lever-arm 19 is pulled down. This downward movement of thelever-arm gradually closes the by-pass valve 18, allowing, however,a'sufticient quantity of gas to flow to the burner to maintain a flameuntil the burner is again elevated. Simultaneously with the lowering ofthe lever-arm the tubular slide 5 and burner 6 are also lowered throughthe medium of the link 2O until the air-opening 12 is closed and theingress of air into the vertical tube 4 shut oft' while the burner isbeing lighted.

In Fig. 3 is illustrated a modified form of burner formed with aperforated dome 22, which extends above the main body ofthe burner, andin order that the burner may be lowered as far as possible upon the tube4 the upper end of said tube is shaped to conform to the inner surfaceof the dome 22 at its center when the burner is lowered, and slots 23areformed in the end of the tube for the escape of gas to the burner. Inthis figure also there is shown a somewhat modified form of springelectrode 15, which is attached to the collar 1 by means of a splitclamp 24, surrounding and insulated from the block.

Without limiting myself to the precise construction and arrangement ofthe parts shown and described, what I claim is 1. The combination with abase adapted to support a chimney and provided with a vertical tubehaving an air-opening, of a tubular slide carrying aburner and movablelon gitudinally upon the tube and a second slide adapted to control theair-opening, substantially as described.

2. The combination with a base supporting a chimney, of a burnernormally surrounded by the chimney, said burner and base beingrelatively movable to bring the burner without the chimney and anigniter arranged to light the burner when it is brought without thechimney, substantially as described.

3. The combination with a base supporting a chimney and provided with avertical tube, of a tubular slide carrying a burner and movablelongitudinally upon the tube, said slide constituting an electrode, anda second electrode supported upon the frame in position to make contactwith the first electrode during the movement thereof upon the verticaltube, vsubstantially as described.

4. The combination with a base supporting a mantle and a chimneysurrounding the mantle, of a burner normally projecting within themantle, said burner and base being relatively movable to bring theburner without the mantle and an igniter arranged to light the burnerwhen it is brought without the mantle, substantially as described.

5. The combination with a base adapted to support a chimney and providedwith a vertical tube, of a tubular slide carrying a burner and movablelongitudinally upon the tube, a cock and a by-pass valve controlling thepassage through the vertical'tube, anv operating-arm for the valve, andconnections intermediate said arm and the tubular slide for loweringsaid slide simultaneously with the closing of the valve, substantiallyas described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
